Trần Đức Anh · Answer

A: Cu(OH)2 $\underrightarrow{t^o}$ CuO + H2O

CuO + 2HCl → CuCl2 + H2O

CuCl2 +2 NaOH → Cu(OH)2 + NaCl

Cu(OH)2 + H2SO4 → CuSO4 + 2H2O

B: Mg(OH)2 $\underrightarrow{t^o}$ 2MgO + H2O

MgO + 2HCl → MgCl2 + H2O

MgCl2 + 2NaOH → Mg(OH)2 + NaCl

Mg(OH)2 + H2SO4 → MgSO4 + 2H2OCâu trả lời: A: Cu(OH)2 $\underrightarrow{t^o}$ CuO + H2O

CuO + 2HCl → CuCl2 + H2O

CuCl2 +2 NaOH → Cu(OH)2 + NaCl

Cu(OH)2 + H2SO4 → CuSO4 + 2H2O

B: Mg(OH)2 $\underrightarrow{t^o}$ 2MgO + H2O

MgO + 2HCl → MgCl2 + H2O

MgCl2 + 2NaOH → Mg(OH)2 + NaCl

Mg(OH)2 + H2SO4 → MgSO4 + 2H2O

Phùng Hà Châu · Answer

A) 1.  Cu(OH)2  $\underrightarrow{to}$  CuO  +  H2O

2.  CuO  +  2HCl  →  CuCl2  +  H2O

3.  CuCl2  +  2NaOH  → 2NaCl  +  Cu(OH)2↓

4.  Cu(OH)2  +  H2SO4  →  CuSO4  +  2H2O

B)  1.  Mg(OH)2  $\underrightarrow{to}$  MgO  +  H2O

2.  MgO  +  2HCl  →  MgCl2  +  H2O

3.  MgCl2  +  2NaOH  → 2NaCl  +  Mg(OH)2↓

4.  Mg(OH)2  +  H2SO4  →  MgSO4  +  2H2OCâu trả lời: A) 1.  Cu(OH)2  $\underrightarrow{to}$  CuO  +  H2O
